Description
Model G Riser Check Valve – 6107090100 – 10″ (250mm) – 10RCR
The Model G Riser Check Valve is a reliable and high-performance valve, specially designed for wet pipe fire protection systems. Featuring grooved end connections, this valve allows for quick and easy installation with approved mechanical couplings. The spring-loaded clapper design effectively minimizes water hammer, ensuring smooth and efficient operation of the system. Its durable construction makes it ideal for both horizontal and vertical installations.
The valve includes factory-tapped drain outlets and gage ports on both sides, providing flexibility for installation and system monitoring. The low-friction loss design optimizes energy efficiency, ensuring minimal operational losses. With a pressure rating of 300 psi (20.7 bar), this valve is suitable for systems requiring higher pressure and performance.
